This is probably a good one for our Support team (email@example.com). To get a quicker response time, be sure to include the following information:
1. Updated Screen Shot of the Server Maintenance Page.
2. Date and Time the issue occurred or first noticed.
3. Log Files (See http://www.tableausoftware.com/support/knowledge-base/creating-tableau-server-log-files for instructions on bundling and sending the log files).
